Our Team

Global Signals Group (GSG) was formed by a team of dedicated Railroad Signal and Communications Engineers who knew they could deliver better engineering designs and service to railroad and light rail service customers worldwide.

Our engineering team has experience and expertise in all aspects of rail crossing and signal projects, including commuter and freight rail systems and light rail/transit systems. The team has experience developing both electrified (OCS and third rail) and non-electrified systems worldwide. Global Signals Group holds professional engineering licences in several states, as well as a C-10 DVBE electrical contractor’s licence.
